Why the image is blurry after increasing magnification? The light intensity decreases as magnification increases. There is a fixed amount of light per area, and when you increase the magnification of an area, you look at a smaller area. So you see less light, and the image appears dimmer. How can you increase the resolution […]

How do you find the missing height of a triangle? Triangle height, also referred to as its altitude, can be solved using a simple formula using the length of the base and the area. Thus, the height or altitude of a triangle h is equal to 2 times the area T divided by the length […]

What body parts do frogs use for protection? Different species of frogs have different kinds of protection. Some have poison glands in their skin, like a chemical warfare tactic !. The skin will secret and cover the body with the poison and this will deter the enemy from eating them. Some use colors to protect […]

What is the major function of muscles? The muscular system is composed of specialized cells called muscle fibers. Their predominant function is contractibility. Muscles, attached to bones or internal organs and blood vessels, are responsible for movement. Nearly all movement in the body is the result of muscle contraction. What are four disorders of the […]

What types of evidence can be used to support a claim? These categories are Fact, Judgment, and Testimony. This page explores the types of evidence used in argumentation. See also the page on logic and argumentation. What to do when you are wrongly accused? Steps to Take If You Are Falsely Accused of a Crime […]

How is ADP converted to ATP? ADP is converted to ATP for the storing of energy by the addition of a high-energy phosphate group. The conversion takes place in the substance between the cell membrane and the nucleus, known as the cytoplasm, or in special energy-producing structures called mitochondria. What is ADP ATP cycle? Within […]

Is 2x a power function? The function y = -5×2 and g(x) = 2×3 are functions with whole numbers as their exponents, so they are power functions….Power functions definition and examples. Parent Function Function Form Reciprocal Function y = 1/ x, y = 1/ x2 Square root Function y = √x Is Y 1 4x […]

How thick does steel need to be to drive on? 1/4 to 1/2 inch How do you calculate the thickness of steel? The formula for weight calculation is: l = length in mm. w = width in mm. t = thickness in mm. η = Specific material density ( e.g.: steel = 7.85 kg / […]

How can we calculate force? What is the formula for force? The force formula is defined by Newton’s second law of motion: Force exerted by an object equals mass times acceleration of that object: F = m ⨉ a. To use this formula, you need to use SI units: Newtons for force, kilograms for mass, […]

Why are blackboards still used? 1. Accessibility: In many developing countries, chalkboards far outnumber whiteboards because they are easier to access. They are very popular in education segments because the running cost of chalkboards is much less expensive compared to markerboards or glass boards. Chalk is also less expensive than markers.” What is the biggest […]
